Robert Plant gets surly when talks turn to a band reunion at yet another 'Celebration Day' press conference

Another day, another Led Zeppelin press conference that gets weird when reporters start needling the band about reuniting. Last time, the legendary rockers were in London, and Robert Plant made an innocuous joke about "doing it" with a correspondant. Har har.

But today in New York, the eternal long-hair went on the offensive when the Associated Press shifted attention from the upcoming Celebration Day DVD, which documents Zep's 2007 reunion gig, to the idea of them getting back together to do, you know, something fresh.

"I mean, we've been thinking about all sorts of things," Plant said, according to Rolling Stone. "And then we can't remember what we were thinking of. Schmuck." This while bassist John Paul Jones and drummer Jason Bonham, son of John, were reportedly uncomfortably silent.

Plant apparently opened the press conference by singing a few lines of Elvis Presley's "Love Me," then grumbling something about a masseuse in the audience posing as a journalist. Even more unpredictably, he praised his bluegrass-playing countrymen: "I love Mumford and Sons."

When a radio host added, "I don't know if [Celebration Day is] going to quench the thirst of those who wished to see you in the flesh," Plant fired back with an insincere, "Sorry!" Yes, shame on the hopeful sap who can't accept that all of this really is about some five-year-old footage.

"We were so happy we [got] it right ... that night," he said of their featured London performance. "But the responsibility of doing that four nights a week for the rest of time is a different thing. We're pretty good at what we do but the tail should never wag the dog, really. If we're capable of doing something, in our own time, that will be what will happen. So any inane questions from people who are from syndicated outlets, you should just really think about what it takes to answer a question like that in one second."

He went on to praise Jason Bonham's sunglasses, and say, "I think expectations are a horrific thing ... So to do anything at all together is such a kind of incredible weight, because sometimes we were fucking awful, and sometimes we were stunning."
